In this research paper, we systematically sought to improve the thermal resistance of polyurethanes by incorporating carboxymethyl cellulose and chitosan, representing a pioneering application of the mixture design approach in their preparation. In this synthesis, hydroxyl-terminated polybutadiene and isophorone diisocyanate (IPDI) were reacted to prepare �NCO terminated prepolymer, which was subsequently reacted with varying mole ratios of CMC and CSN to develop a series of five PU samples. The prepared PU samples were characterized using the Fourier-transformed infrared spectroscopic technique. Thermal pyrolysis of PU samples was examined using thermal gravimetric analysis (TGA). It was observed that, among all the samples, PUS-3 showed remarkable thermal stability over a wide temperature range. A comprehensive statistical analysis was conducted to substantiate the experimental findings. It was estimated that CMC and CSN significantly enhance the thermal stability of the samples when involved in an interaction fashion. The ANOVA Table for the mixture design demonstrates that over 90 of the total variation in thermal stability is explained by the mixture model across a wide temperature range. Moreover, PSU-3 exhibited 4 more thermal stability over a wide range of temperatures on average, as compared to contemporary samples. © 2024 Elsevier B.V. date: 2024 publisher: Elsevier B.V. official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85190534247&doi=10.1016%2fj.ijbiomac.2024.131441&partnerID=40&md5=57d27fbde1981a3ca8a96d6ddee87444 id_number: 10.1016/j.ijbiomac.2024.131441 full_text_status: none publication: International Journal of Biological Macromolecules volume: 267 refereed: TRUE issn: 01418130 citation: Javaid, M.A. and Cheema, S.A. and Nasir, N. and Ahmad, S. and Hussain, M.T. and Tanveer, Z. and Mustafa, M.Z.U. and Tahir, U. and Ali, S.
